Chapter: Hajj on behalf of one who is incapable of doing it because of chronic illness, old age and the like, or on behalf of one who has died
Hadith Number 1334
'Abdullah b. 'Abbas reported that while al-Fadl b. Abbas had been riding behind Allah's Messenger (ﷺ) a women of the tribe of Khath'am came to him (to the Holy Proppet) asking for a religious verdict. Fadl looked at her and she looked at him. Allah's Messenger (ﷺ) turned the face of al-Fadl to the other side. She said
Messenger of Allah, there is an obligation from Allah upon His servants in regard to Hajj. (But) my father is an aged man; he is incapable of riding safely. May I perform Hajj on his behalf? He said: Yes. It was during the Farewell Pilgrimage.

Fadl reported that a woman of Banu Khath'am said
Messenger of Allah, my father is very old. There is an old obligation of Hajj upon him from Allah, but he is not capable of sitting on the back of the camel. Thereupon Allah's Apostle (ﷺ) said: Perform Hajj on his behalf.
